A large twelve-week study found that garlic supplementation reduced the number of colds by 63 percent versus placebo. That is awesome by itself, but even better when you consider the average length of cold symptoms for those who were sick was also reduced, from 5 days to just 1.5 days in the group taking garlic. Another study backed up those results and found that a high dose of garlic extract can reduce the number of days someone feels sick with cold or flu by 61 percent. To get the maximum benefit, load up on garlic in the winter or if anyone in your house is getting the sniffles.
